481  Linux Stuff / Kernel / Re: 2.6.30-rc2 and 2.6.30-rc3 new releases on: April 24, 2009, 07:00:47 PM
mavr15, In a lot of cases you can get away with using a previous kernel with new modules, but there are cases where it just won't work.  Apparently this is one of those cases.  When you enable a new module it "may" enable features (export symbols) that weren't exported before the module was enabled.  The most prudent approach is to flash the matching kernel if the modules have been changed/updated.

mavr15, Were you getting "unknown symbol" when you modprobed tun?  I actually tested tun on my system and it loaded fine when I modprobed tun.  I wonder if you were using the previous version of the kernel that was build without tun with the new Modules.  That could cause a potential "unknown symbol".

In any case the 2.6.22.19 kernel should work just fine.

I'm pretty sure it's been submitted to the maintainers.  It might take a while to trickle up into the official kernel.  Hopefully the fix will be in the official .30 kernel.

Call the power company and see if you can get them to turn your power off and on? Wink  Barack Obama could get them to do it. hehe

I agree that SD isn't as fast as USB on the Sheeva.  I did some testing with results similar to yours.  The interesting thing is that even though SD isn't as fast as USB, it's still WAY faster than JFFS2 running from flash.

Right now I'm running with an SD root and a USB /home, which is a nice combo for a development Sheeva.

If you can get the pronged piece to move at all you can usually just put a prying device in the gap and pry it loose.  Seems to me we used a butter knife.  It does have a catch on the underside that makes it a bit of a bear to remove it.

All I can say is wow.  When you move your root filesystem to SD it is way fast compared to JFFS2.  It moves wear and tear off your Flash to replaceable SD.  It's beautiful that you could pop out the SD from a SheevaPlug, pop it into an SD reader on a standard machine and create a duplicate SheevaPlug install in minutes.  I'm using an 8Gig SD formatted with EXT2.  My theory is that journaling filesystems such as EXT3, EXT4, JFS, XFS create undo wear on flash media.  So I stick with plain 'ol EXT2 with noatime specified in fstab.

All you need to do is:

"cp -ax / /Whereever/SdIsMounted"
In U-Boot change boot_args to "root=/dev/mmcblk0p1".

I just added the tun driver to 2.6.30-rc2 and 2.6.30-rc3.  It was already in 2.6.22.19.
489  Linux Stuff / Kernel / Re: 2.6.30-rc2 and 2.6.30-rc3 new releases on: April 23, 2009, 11:57:51 PM
The first time I rebooted after flashing.  I had a similar response.  In my case A hard reset fixed the problem and It's been working fine ever since.  The most interesting problem I had was the kernel not being able to identify what the root filesystem type was.  That's where the "rootfstype=jffs2" came in.

I'd suggest using tftp to boot the kernel if you're still having problems and then do a  reflash.

Yes.  The configs are now online.  BTW, I also created a patches subdirectory for patches that are applied.

Which modules are you needing?  If they're generally useful, I'd be happy to add them to the default build.
491  Linux Stuff / Kernel / 2.6.30-rc2 and 2.6.30-rc3 new releases on: April 22, 2009, 10:33:39 PM
Kernel and modules are available from the following locations:

IPV4: http://sheeva.with-linux.com/sheeva/

IPV6: http://sheeva6.with-linux.com/sheeva/

Features IPV6, CIFS, NFS4, EXT3, EXT4, JFS, XFS, FUSE(for ntfs-3g), usb-serial, uvcvideo.

my usb-serial  driver has been patched to allow full-speed downloads using high-speed wireless modems, (EVDO for example) as per this thread. http://www.evdoforums.com/thread4381.html Anyone interested in testing out EVDO modems with SheevaPlug?

uvcvideo is not supported in the 2.6.22.19 kernel.

You're question is a little hard to follow, but I think I get the jist of it.  Here is what I think you're looking for.

There are three sections in flash.  1. U-Boot, 2. Kernel image, 3. JFFS filesystem.

On bootup:
1. U-Boot copies itself from flash into ram and continues execution from ram
2. U-Boot copies the kernel image from whereever (typically flash) to ram
3. U-Boot executes the kernel from ram (the kernel reclaims the ram previously used by U-Boot)
4. The kernel reads the JFFS filesystem from flash (this part is NOT copied to ram, but is accessed directly from flash)

In a nutshell, you can't use any old filesystem for the flash filesystem.  JFFS is specifically designed to R/W files stored in flash.

I just added usb-serial support to the the kernel  image/modules located here.

IPV4: http://sheeva.with-linux.com/sheeva/

IPV6: http://sheeva6.with-linux.com/sheeva/

If you want to test it (as root) just download the README to your sheevaplug.  chmod 755 README. ./README.  It'll install the modules and the new uImage.  After a successful flash just reboot.

my usb-serial  driver has been patched to allow full-speed downloads (1.5MBit) using high-speed wireless modems, (EVDO for example) as per this thread. http://www.evdoforums.com/thread4381.html Anyone interested in testing out EVDO modems with SheevaPlug?

My 2.6.22.19 images have been updated to incorporate cifs.

To use: apt-get install smbfs.  Add cifs to /etc/modules.
